So I should be trying squid 3 instead of 2.5? An example config file would be nice, as I dont know how to ad the "Front-End-Https: yes" header part. Thanks for the help tho.

Some of the objects within the pages are http You need to make Squid add the "Front-End-Https: yes" header when acting as a SSL frontend to OWA. This is a OWA specific header, telling OWA that there is an SSL gateway infront of it. > Has anyone on this list setup OWA behind a squid reverse proxy? Yes, but with a quite different Squid (in these aspects more resembling Squid-3.0 than 2.5). Regards Henrik
